Title: Improvements relating to shuttering for use in building concrete structures
IPC: E04G11/18
Filed: 1920-09-22
Abstract: 168,258. Shingleton, L. Sept. 22, 1920. Moulding in situ.- Walls are erected course upon course by the use of metal shuttering and supports. The supports a are of channel-iron or other section and are notched at intervals to correspond with the vertical disposition of the wall ties b by which they are adapted to be engaged and supported, and the metal shuttering is made in sections to fit between the wall ties disposed horizontally and has inturned upper edges to rest on the supports. The outer-shuttering supports a are supported on bolts c carried by vertical uprights d. The shutters may be plain sheets with angleirons on their upper edges and pivoted catches r to engage the supports, and in this case the catches may be turned to rest on the top of the cast concrete while the supports are disengaged from the ties or bolts and raised to a higher level and re-engaged with the higher ties or bolts in the concrete; the shutters are then raised to rest on the supports. Recessed distance-pieces, Fig. 3, are used to separate the top ends of the shutters and supports while the concrete is being poured. Finger holes p are provided in the top ends of the uprights to enable them to be easily handled.

Title: Vehicle anti-locking braking systems
IPC: B60T8/70
Filed: 1973-06-07
Abstract: 1376279 Anti-skid systems AUTOMOBILES CITROEN SA 7 June 1973 [13 June 1972] 27201/73 Heading F2F In a vehicle anti-skid system for at least one wheel a first pulsating electrical signal with a frequency proportional to wheel rotation is compared with a second pulsating electrical signal representing a predetermined fraction of the vehicle speed to produce an error signal from a digital comparing means from which is produced a control signal as a function thereof to actuate control means to reduce pressure to pressure-operated brakes for the wheel to offset wheel slip exceeding a predetermined value. In Fig. 2, which shows a system for a single wheel, wherein an electromagnetic pick-up 9 supplies a pulsed signal to a pulse shaping circuit 10, in turn supplying a signal to a memory counter 12, also receiving clock pulses at a lower frequency, to count the pulses from circuit 10 between successive clock pulses. The output is passed to the comparing means in the form of a differential counter 16 and is compared with a similarly produced signal representing vehicle speed but with a predetermined ratio factor of less than one which may be constant or variable as a function of vehicle speed. The original vehicle speed signal may be obtained from the wheel speed signal by a generator 21, e.g. comprising a shift register, comparing wheel and vehicle speeds and providing an output depending on which is the greater. The comparator output is fed to a converter 18 which supplies pulses at a frequency determined by a clock 11, which supplies the parts 12, 21, pulses of varying widths depending on the differential counter output which is digital, e.g. having four possible values in binary code. The converter 18 has a frequency multiplier and a transfer device acting on the clock pulses, feeding a memory unit, e.g. 2-bit, the outputs thereof being connected to an OR gate providing the output signal via an amplifier 19 to an electromagnetic valve 5, 20 which has a variable opening, according the value of the signal, for fluid pressure from a pump 4 via a pedal operated valve 6. In Fig. 4, the vehicle speed signal is computed from a comparison of all the vehicle wheels' speeds, the highest being used therefor. Each vehicle wheel speed is compared therewith, only one such comparison being shown. A shift register 29 in combination with a shift register 31 and differential counters 30, 32 provide signals analogous to first and second order differentiation of the input from the counter 16, whereas the register 29 in combination with shaft registers 35, 37 and adder counters 34, 36 provide signals analogous to first and second order integration of the input. These signals and the input are fed into a logic matrix 38 to control the electromagnetic valve anticipating variations between the brake wheel speed and optimum slip values. Alternatively, the control is made via valves for each axle, the logic matrix 28 output supplying a signal corresponding to the lower speed value of the two wheels in each instance.

The plant comprises a generator 1, carburettor 2, superheater 3, wash box 4, condenser 5, wash box 6, and condenser 7. Primary air is supplied through conduit 9, secondary air through 13, steam through pipe 10 or 11, or for back running through pipe 12, and oil through pipe 27. After the usual blow, the stack valve 29 is closed and an up-run made, the water gas passing through the wash box 4, condenser 5, and connections 19, 21 to storage, or a down run may be made. Oil is then vaporized in the carburettor, and the oil vapours and gas passed through the superheater, steam being admitted through pipe 28 to assist in carrying along the oil gas, which passes through wash box 4 and condenser 5, where some tar and light oils are removed. The oil gas is then passed by pipes 19, 23 through the generator, from which the " reformed " oil gas passes by connection 32 to the wash box 6 and condenser 7 where further tar and light oils are collected. The condenser 5 may be bye-passed by connection 30.
